Nice To Haves

Experience as an embedded product security engineer.
Experience with automotive or vehicle cybersecurity and regulatory type approval (ISO/SAE 21434, UNECE R155/R156) and secure over-the-air software updates is strongly preferred.
Preferred background securing in-vehicle and telematics networks—CAN J1939/CAN FD with SecOC, Automotive Ethernet/SPE (100Base-T1, 10Base-T1S) with MACsec and TLS 1.3, and MQTT with mutual TLS.
Familiarity with ISO/SAE 21434 TARA, UNECE R155 and R156, ISO 24089, and/or GB 44495-2024 type-approval expectations.

Responsibilities

Assess product security risks in a maintained register, develop comprehensive mitigation strategies, and evaluate technical and business trade-offs.
Apply the Secure Development Lifecycle and lead product security processes including architectural analysis, threat modeling, security DFMEA, penetration testing, attack modeling and simulation, cybersecurity type-approval activities including TARA per ISO/SAE 21434, and data privacy impact assessments.
Identify, evaluate, and verify security issues discovered through automated testing, penetration testing, and customer feedback. Maintain and track closure of vulnerability backlogs.
Interpret and enforce product security requirements, conduct vulnerability reviews, and ensure compliance with automotive and industrial cybersecurity regulations and standards (UNECE R155, UNECE R156, ISO/SAE 21434, ISO 24089, GB 44495-2024, IEC 62443, NIST, and applicable regional data-privacy laws).
Support vehicle cybersecurity and software-update type approval by maintaining Cyber Security Management System (CSMS) and Software Update Management System (SUMS) processes and evidence aligned to regulations and standards.
Define and validate secure over-the-air and service-tool update paths, covering secure boot, hardware root of trust, PKI and certificate management, code signing, and anti-rollback protection across the zonal architecture and independent modules.
Apply privacy-by-design and support data-protection impact assessments to meet regional obligations such as GDPR, CCPA, LGPD, the EU Data Act, and California SB-327.
Monitor outputs and effectiveness from all security tools integrated within the software development lifecycle.
Advise, guide, and mentor cross-disciplinary engineering teams during the design, review, and implementation of security features.
Validate that software meets all functional, security, regulatory (cybersecurity compliance), and quality benchmarks particularly within industrial and transportation environments.
